Sez who?

Some linguist, either at university or in some book I read. I typed de facto not de jure. What are you choices? New England or Southern (and which variety)?

Googling around, I see that some linguists, e.g., Prof. Wm Labov, make a distinction between North Central, Midland, and West dialects of American English, which I would've grouped into the Midwestern dialect, so I guess I should update my sentence to say: The West dialect of American English, on account of Hollywood , its use in the media.

Ceci n'est pas un seing.
